Wide area networks for surveying applications, such as seismic acquisition, have been witnessing a significant increase in node density and area, where large amounts of data have to be transferred in real-time. While cables can meet these requirements, they account for a majority of the equipment weight, maintenance, and labor costs. A novel wireless network architecture, compliant with the IEEE 802.11ad standard, is proposed for establishing scalable, energy-efficient, and gigabit-rate backhaul across very large areas. Statistical path-loss and line-of-sight models are derived using real-world topographic data in well-known seismic regions. Additionally, a cross-layer analytical model is derived for 802.11 systems that can characterize the overall latency and power consumption under the impact of co-channel interference. On the basis of these models, a Frame Aggregation Power-Saving Backhaul (FA-PSB) scheme is proposed for near-optimal power conservation under a latency constraint, through a duty-cycled approach. A performance evaluation with respect to the survey size and data generation rate reveals that the proposed architecture and the FA-PSB scheme can support real-time acquisition in large-scale high-density scenarios while operating with minimal power consumption, thereby enhancing the lifetime of wireless seismic surveys. The FA-PSB scheme can be applied to cellular backhaul and sensor networks as well.

通过广域网中的帧聚合实现节能毫米波回程


用于地震采集等勘测应用的广域网的节点密度和面积显着增加，需要实时传输大量数据。虽然电缆可以满足这些要求，但它们占设备重量、维护和人工成本的大部分。提出了一种符合 IEEE 802.11ad 标准的新型无线网络架构，用于在非常大的区域内建立可扩展、节能和千兆位速率的回程。统计路径损耗和视线模型是使用已知地震区的真实地形数据得出的。此外，还为 802.11 系统导出了跨层分析模型，该模型可以表征同信道干扰影响下的整体延迟和功耗。在这些模型的基础上，提出了帧聚合节能回程（FA-PSB）方案，通过占空比方法在延迟约束下实现近乎最佳的节能。对调查规模和数据生成率的性能评估表明，所提出的架构和 FA-PSB 方案可以支持大规模高密度场景中的实时采集，同时以最小的功耗运行，从而提高了设备​​的使用寿命。无线地震勘测。 FA-PSB 方案也可以应用于蜂窝回程和传感器网络。
